[FEAT]: Implement an endpoint to get all comment on a blog post

[dhamolahedonist]

Description:

Implement an endpoint to retrieve all comments on a specific blog post. This feature should ensure that users can fetch all comments associated with a particular blog post.

Acceptance Criteria:

API Endpoint Implementation:

• The endpoint should be accessible at /api/v1/blogs/:blog-id/comments.
• The endpoint should handle GET requests.

Authorization:

• Ensure that only authenticated users can access the endpoint.
• Validate the token received in the request to authenticate the user.

Data Handling:

• On successful request, fetch all comments associated with the specified blog post from the database.
• Each comment should include relevant details such as the commenter's name, the comment text, and the timestamp.

Response:

• On success: The API should return a 200 OK status code with the list of comments.
• On failure: The API should return appropriate status codes and messages for different error scenarios (e.g., blog post not found, unauthorized access).

Request Example:

GET /api/v1/blogs/123/comments
Authorization: Bearer <jwt_token>

Successful Response Example:

{
  "message": "Comments retrieved successfully",
  "status": 200,
  "comments": [
    {
      "id": 1,
      "author": "Jane Doe",
      "text": "Great post!",
      "timestamp": "2024-07-24T10:00:00Z"
    },
    {
      "id": 2,
      "author": "John Smith",
      "text": "Very informative.",
      "timestamp": "2024-07-24T11:00:00Z"
    }
  ]
}

Error Response Example:

{
  "message": "Unauthorized",
  "status": 401
}

or

{
  "message": "Blog post not found",
  "status": 404
}

or

{
  "message": "Internal server error",
  "status": 500
}

Purpose:

Enable users to retrieve all comments on a specific blog post, providing a way to view discussions and feedback associated with the post.

Requirements:

• Develop server-side logic to handle the retrieval of comments for a blog post.
• Implement authorization checks to validate the user's JWT token.
• Ensure comments are properly fetched and returned in the response.

Expected Outcome:

• Users can fetch all comments on a specific blog post, with each comment's details being returned in the response.

Status Codes:

200: Comments retrieved successfully,
401: Unauthorized access due to invalid token,
404: Blog post not found,
500: Internal server error,

Testing:

• Write unit tests to verify that the endpoint correctly retrieves comments for a blog post.
• Test authorization to ensure only authenticated users can access the endpoint.
• Perform integration testing to confirm that comments are correctly fetched and returned in the response.

The request params should be in kebab case and the acceptance criteria should be checklists
